Synopsis
It is 1984, fifteen years since the nuclear war between the United States and the Soviet Union devastated the entire Northern Hemisphere of the planet Earth, nuclear scientists Professor Doctor Lee Richardson and Comrade Professor Alexis Petrovitch Pitov are working together on a project in Argentina. During their research, they have created fifteen kilograms of negamatter iron, and they are going to drop it from space to see what happens.

The resulting explosion has a very distinctive signature, and Dr. Richardson realizes that that signature is the same as the one that occurred at Auburn, New York. The American government had assumed that the explosion was the result of a premeditated attack by the Soviets, and had retaliated, resulting in a general exchange of nuclear weapons. During the course of analyzing the Argentinean explosion Dr. Richardson realizes that the “Auburn Bomb” was not a bomb after all, but a negamatter meteor.
